Blackwater/Alamo: I made those mounts you see in the pics.My gun has a Redfield Olympic rear sight However it was a design modification of a mount that Redfield made back in the day to mount their Series 70 Receiver Sights to a #4 Enfield. See Pics below. They can be adapted for either Redfield or Lyman style sights with a flat base, like for a levergun. IE; Lyman 66LA.
As far as the front sight is concerned some white paint on the back face is a good way to go. I also really like the XS White Line Front Sights as they are highly visible against most backgrounds. Matching the dovetail would be the rub there, but not impossible.
As far as seeing the thing, Your eye can only focus on one thing at a time. We were all trained to shoot with Open Sights where we were changing focus between the front, rear, and target constantly. nobody our age can do that.
I didn't find out about focusing solely on the Front Sight until about 12 years ago. That is the secret! With an Aperture Sight, you simply focus on the Front Sight and put the sight on the fuzzy target, there is no lining up needed.
With Aperture Sights the size of the hole controls the focus between your eye and that distance to the Front Sight. IE: Focal Length. Your glasses do the same thing. The trick is to use different apertures or a Merit Adjustable disc to establish what size you need.
If you are using a Red Dot Sight once again you only focus on the dot. Put the dot on the target and let fly. It is the fastest way to acquire a target simply because you only have to concentrate on one thing,,, the dot. I was blown away how fast I could get on target with my Carbines. I found myself having to tell myself to pull the trigger as I had already been on target for some time before I figured out I could just pull the trigger. It was Dot pause bang, but it turned into Dot, Bang, Dot, Bang, Dot, Bang! No thinking involved. Seeing the dot on target triggers the trigger. Not a separate thought to pull the trigger.
It's scary fast and you pick it up quick!
I can make these mounts if you would like one. I only need your sight in hand to make sure it works right on the gun.
